Infineon TLE9252VLC: A High-Speed CAN Transceiver for Automotive Network Interfaces

The increasing complexity of modern vehicle architectures demands robust and reliable communication networks. At the heart of these in-vehicle networks (IVNs), the Controller Area Network (CAN) remains a cornerstone technology. The Infineon TLE9252VLC stands out as a state-of-the-art high-speed CAN transceiver, engineered to meet the stringent requirements of next-generation automotive applications.

This transceiver serves as the critical interface between a microcontroller's protocol controller and the physical CAN bus. It is designed for high-speed CAN networks operating at data rates up to 2 Mbit/s, supporting the high-bandwidth needs of powertrain, chassis, and body control modules. A key feature of the TLE9252VLC is its robust ESD protection, exceeding 8 kV according to IEC 61000-4-2, which is essential for the electrically harsh automotive environment. This ensures unparalleled resilience against electrostatic discharge, a common cause of IC failure.

Furthermore, the device incorporates advanced functionality to enhance network integrity and vehicle safety. It offers comprehensive diagnostic capabilities, including thermal shutdown, undervoltage detection, and permanent dominant detection. These features allow the system to monitor the health of the transceiver itself and flag potential errors on the bus, contributing to higher system-level functional safety and aiding in the development of systems targeting ISO 26262 ASIL compliance.

The TLE9252VLC is also optimized for low-power operation, featuring a dedicated low-power mode with very low current consumption. This is particularly vital for today's vehicles, where energy efficiency is paramount, especially in applications that must remain alert even when the ignition is off. Its compact VSSOP-14 package makes it suitable for space-constrained applications, offering a perfect blend of performance and integration.

ICGOODFIND: The Infineon TLE9252VLC is a premier solution for automotive designers, masterfully combining high-speed data transfer, exceptional robustness against electrical hazards, and sophisticated diagnostic features. It is an ideal choice for building reliable, safe, and efficient network interfaces that are critical for the evolution of connected and autonomous driving.
